Manchester City's youngsters have joined in the "mannequin" craze by freezing one of their indoor gym sessions.

The young Blues played their part in the latest fad after the first team famously joined in the Harlem Shake meme which swept the world in 2013.

The craze consists of a video of people seemingly frozen to the spot as the cameraman walks amongst them.

And City's elite development squad did theirs in the difficult setting of the gym at the City Football Academy - and goalkeeper Billy O'Brien had the toughest task of all!

The Wales under-21 international is seen hanging from an overhead bar with his legs at a 90-degree angle to his body in the video, tweeted by Thierry Ambrose.

James Horsfield almost ruins the whole thing by bursting out laughing, while Ambrose himself – just getting back to full fitness after a long injury lay-off, and defender Cameron Humphreys also feature in the short vid.
